He’s only three, but he can count to 200 and name every country on the planet

Sherwyn Sarabi, from Royston, Barnsley, is ranked among the top one per cent of the world’s cleverest people after tests revealed he had an IQ of 136.

His mother, Amanda Sarabi, said she was really proud of her gifted son, who she described as “amazing”.

Sherwyn, who has a reading age of six, began speaking at the age of 10 months and was talking in sentences at 20 months.

By the age of two, Sherwyn could read, count to 200, recognise and name countries, flags, planets in the solar system, parts of the body and internal organs.

Mrs Sarabi, 36, said: “His general knowledge is amazing. He knows about everything. It’s not like talking to a three-year-old. He doesn’t even watch children’s programmes, he watches the news.

“The weather is his favourite, especially the world weather. He loves that.”

She added: “We take every day as it comes. I’ve never forced teaching anything on to him. If he comes to me and asks me about a topic, I teach him to the best of my knowledge.”

Mrs Sarabi said she and her husband, Davoud, 37, who was studying construction management until he was involved in an accident, were well-educated but “nothing extraordinary”.

She said they first noticed Sherwyn’s interest in learning when he was 18 months old but his intelligence seemed normal to them until other people pointed out how unusual it was.

After his third birthday, Sherwyn was tested on the Wechsler Pre-School and Primary Scale of Intelligence, which placed him in the 99th percentile with an IQ of 136.

The normal range using this test is between 85 and 115, with the average IQ being 100.

Sherwyn has also started attending the Rastrick Independent School, in Brighouse where a special lesson plan has been designed for him.
